Firefox-mienskipsfoarum

I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

I want to downgrade to a previous version without having to create a new profile. I don't want the Firefox logo on the default new tab page, and I tried to change it in the about:config list but that didn't work even after a complete computer restart. It worked in the previous version. I do not want to create a new profile. My current one is just fine. How can I do that? Thank you!

For the past few days when I use Firefox and Thunderbird my entire screen will randomly start to flicker, at times very quickly and rarely the entire screen goes black for second or two. This behavior immediately stops when I close the app. It does not happen with any other app. I've tried disabling hardware acceleration in Firefox and that didn't help. Both apps are on the latest version and I also updated my video driver. Tried removing the two add-ons I have. I'm on Windows 11 Firefox 136.0.

Dear support person,

When streaming video games on multiple platforms i use a dock from a website called social stream Ninja. This opens a browser page that shows chats from 3 platforms, Twitch, Youtube and Kick. I have a dual PC setup, so i game on the first PC with the second PC running the actual stream through a capture card.

When i go into SteamVR, i add a desktop panel with that exact dock/webpage on firefox, but the page "pauses" and chat doesn't update anymore. I thought this was a focus issue, so i tried this plugin = Always active Window - Always Visible

Sadly FireFox still doesn't update the page, therefore stream chat doesn't show up, the page pauses. A sort of work-around is running the game in borderless window, but this is VR, and eats up quite the bit of performance, fullscreen is preferred. The borderless window works on Assetto Corsa VR, but on Dirt Rally 2 VR it doesn't, so I really need FireFox to update the page in the background.

I've been tearing my hair out trying to find a solution, the 'focus' plugin was my best idea.

Any chance you could help me?

Kind Regards,

Carlo

In the last 2 weeks you tube or yahoo on firefox either times out or drops about 30 minutes in but when I use you tube or yahoo on Google I don't have this problem. Is there a problem with an extension or security issue that would cause this? Did an update cause this? It's frustrating. It's been happening to my husband on his desktop also. It will tell us we're not connected but when I go the the router it shows connected. I have to exit out of the browser and reload and everything is fine for about 30 minutes and then I have to exit and reload which requires me to sign in again. Just wondering if an update caused this.
